How to unlock the For the Utopia! achievement in Super Street Fighter IV - Definitive Guide
Abusing focus attacks works very well as the AI on normal usually don't break it. Follow it up with your best combo/attack/throw and you should be golden. Time that on your opponents wake-up and you'll have a hard knock-down loop.
Also, if you have an extra controller - keep that on and be prepared to push start if you can't see yourself win the match. That'll bring "a new challenger" I.E the second controller, beat it and you'll restart at the same opponent as you chickened out on.
I use 1 rond since it's faster.
Apparently you don't have to worry about losing to the characters after Seth (Akuma/Gouken/Evil Ryu/Oni) as pointed out by Trilby Burglar in the other solutions.
Good luck.
For the Arcade Mode trophies, you'll want to have the following settings:
Rounds: 1
Timer: 99
Difficulty: Medium
These are the minimum requirements if you want to complete Arcade Mode as fast as possible. 99 seconds gives you plenty of time to beat your opponent without losing to lower health, and medium difficulty is the lowest you can go without voiding the trophy. Also, keep a second controller handy so that you can hit the start button in the event that you are about to lose a match. This will allow you to beat the idle second player and continue the arcade without using a continue as per the trophy requirements. One general tip I can give is that knocking down the CPU and following with a grab when they stand is a decent way to deal some damage. I always try to follow a knockdown with a grab.
Rolento is a very nimble character that features a move-set heavily involving jumping around and fast combos. I found him to be one of the more "noob friendly" characters in the game since his combos are rather easy to chain and pull off. He's very mobile which is good for closing the gaps when you're fighting a character with ranged attacks such as Ryu or Cody. He also features a sliding Heavy Kick move that is effective at knocking down opponents from a distance. His Patriot Circle move is strong and great for creating a solid combo since it can be done 3 consecutive times. Some effective combos I found were:
Mekong Delta Escape > Air Hard Punch > Patriot Circle
> During the Mekong Delta Escape > () x3
The above can also be followed by his super combo, Mine Sweeper. You can also switch the Patriot Circle for an Ultra Combo if it's available.
Stinger > Crouching Hard Kick > Grab
( or or ) > > when CPU gets up
Mekong Delta Air Raid > Crouching Hard Kick > Grab
then > > when CPU gets up
